Short Signatures from the Weil Pairing

TLDR
A short signature scheme based on the Computational Diffie-Hellman assumption on certain elliptic and hyperelliptic curves is introduced, designed for systems where signatures are typed in by a human or signatures are sent over a low-bandwidth channel.
Abstract
We introduce a short signature scheme based on the Computational Diffie-Hellman assumption on certain elliptic and hyperelliptic curves. The signature length is half the size of a DSA signature for a similar level of security. Our short signature scheme is designed for systems where signatures are typed in by a human or signatures are sent over a low-bandwidth channel.

Efficient Construction of (Distributed) Verifiable Random Functions.

TL;DR: In this paper, the authors give the first simple and efficient construction of verifiable random functions (VRFs) based on decisional Diffie-Hellman (DDH) assumption on certain groups where the regular DDH assumption does not hold.

The function field sieve in the medium prime case

TL;DR: This approach is an alternative to a recent paper of Granger and Vercauteren for computing discrete logarithms in tori, using efficient torus representations, and shows that when q is not too large, a very efficient L(1/3) variation of the function field sieve can be used.

Ring Signatures without Random Oracles.

TL;DR: In this paper, a ring signature scheme based on bilinear pairings is proposed, which is proven to be secure against adaptive chosen message attack without using the random oracle model.

A novel ID-based authentication framework with adaptive privacy preservation for VANETs

TL;DR: This paper proposes a novel ID-based authentication framework with adaptive privacy preservation for VANETs, where adaptive self-generated pseudonyms are used as identifiers instead of real-world IDs.

Random oracles are practical: a paradigm for designing efficient protocols

TL;DR: It is argued that the random oracles model—where all parties have access to a public random oracle—provides a bridge between cryptographic theory and cryptographic practice, and yields protocols much more efficient than standard ones while retaining many of the advantages of provable security.

Identity-Based Encryption from the Weil Pairing

TL;DR: This work proposes a fully functional identity-based encryption (IBE) scheme based on bilinear maps between groups and gives precise definitions for secure IBE schemes and gives several applications for such systems.

The Arithmetic of Elliptic Curves

TL;DR: It is shown here how Elliptic Curves over Finite Fields, Local Fields, and Global Fields affect the geometry of the elliptic curves.

A digital signature scheme secure against adaptive chosen-message attacks

TL;DR: A digital signature scheme based on the computational difficulty of integer factorization possesses the novel property of being robust against an adaptive chosen-message attack: an adversary who receives signatures for messages of his choice cannot later forge the signature of even a single additional message.
